Improved SEO and Search Rankings: Google and other search engines like websites that load fast. If the image size is big, then the website loads slowly. That’s why the image should be compressed. It helps to open the site faster and also improves ranking in search.
Reduced Storage and Bandwidth Usage: Smaller image files take less server storage and less bandwidth; this saves money in hosting cost, and it is very useful for websites that have more media content.
Enhanced Performance on Mobile Devices: Now, most people use mobile phones to browse websites. So your images should load faster and also look proper on small screens. Compressed images make the site work smoothly on all devices without any loading issues.
